5-(Carboxymethylaminomethyl)-2-thiouridine, a new modified nucleoside found at the first letter position of the anticodon
Received March 11, 1981. The structure of a modified uridine derivative which was detected at the first letter position of the anticodon of Bacillus subtilis tRNALys was determined to be 5-(carboxymethylaminomethyl)-2-thiouridine. The determination was mainly based in its ultraviolet absorption spectra and mass spectrometric analysis of the trimethylsilyl derivative.
